摘要

我们利用最新的快速射电暴观测数据研究了可变查普里金气体模型参数的宇宙学约束,并将结果与以前利用SNe Ia(Pantheon+SHOES)、伽马射线暴、重子声学振荡和哈勃参数观测数据获得的约束进行了比较。变查普里金气体模型与这些数据集是兼容的。我们利用 FRB 数据集获得了对模型参数 \(B_{s}\) 和 \(n\) 的更严格约束。通过使用马尔科夫链蒙特卡洛(MCMC)方法,我们得到:\(B_{s}\)=\(0.18\pm 0.10\), \(n=1.10\pm 1.15\) and \(H_{0}\)=\(70.46\pm 0.66) with the SNe Ia data set, \(B_{s}\)=\(0.09\pm 0.06\), \(n= 0.44\pm 0.89\) and\(H_{0}=70.57\pm 0.64\) with the FRB data set, \(B_{s}\)=\(0.16\pm 0.用 BAO 数据集,\(B_{s}\)=\(0.05\pm 0.000\), \(n=1.46\pm 0.23\) and\(H_{0}\)= \(70.和 GRB 数据集的(B_{s}\)=\(0.20\pm 0.11\), (n=1.25\pm 1.17\) 和 (H_{0}\)=\(70.37\pm 0.64\).从这些数据集中观察到了\(H_{0}\)的良好一致性。

Variable Chaplygin gas: Constraining parameters using FRBs

Variable Chaplygin gas: Constraining parameters using FRBs

We investigate cosmological constraints on the Variable Chaplygin gas model parameters with latest observational data of the Fast Radio Bursts and compare the results with previous constraints obtained using SNe Ia (Pantheon+SHOES), Gamma Ray Bursts, Baryon Acoustic Oscillations and Hubble parameter observational data. The Variable Chaplygin gas model is shown to be compatible with these datasets. We have obtained tighter constraints on model parameters \(B_{s}\) and \(n\), using the FRB data set. By using the Markov chain Monte Carlo (MCMC) method we obtain, \(B_{s}\)=\(0.18\pm 0.10\), \(n=1.10\pm 1.15\) and \(H_{0}\)= \(70.46\pm 0.66\) with the SNe Ia data set, \(B_{s}\)= \(0.09\pm 0.06\), \(n= 0.44\pm 0.89 \) and \(H_{0}=70.57\pm 0.64 \) with the FRB data set, \(B_{s}\)=\(0.16\pm 0.11\), \(n=1.06\pm 1.25\) and \(H_{0}\)= \(70.37\pm 0.65\) with the BAO data set, \(B_{s}\)=\(0.05\pm 0.000\), \(n=1.46\pm 0.23\) and \(H_{0}\)= \(70.21\pm 0.57\) with the H(z) data set and \(B_{s}\)=\(0.20\pm 0.11\), \(n=1.25\pm 1.17\) and \(H_{0}\)= \(70.37\pm 0.64\) with the GRB data set. A good agreement for \(H_{0}\) is observed from these data sets.

期刊介绍: Astrophysics and Space Science publishes original contributions and invited reviews covering the entire range of astronomy, astrophysics, astrophysical cosmology, planetary and space science and the astrophysical aspects of astrobiology. This includes both observational and theoretical research, the techniques of astronomical instrumentation and data analysis and astronomical space instrumentation. We particularly welcome papers in the general fields of high-energy astrophysics, astrophysical and astrochemical studies of the interstellar medium including star formation, planetary astrophysics, the formation and evolution of galaxies and the evolution of large scale structure in the Universe. Papers in mathematical physics or in general relativity which do not establish clear astrophysical applications will no longer be considered. The journal also publishes topically selected special issues in research fields of particular scientific interest. These consist of both invited reviews and original research papers. Conference proceedings will not be considered. All papers published in the journal are subject to thorough and strict peer-reviewing. Astrophysics and Space Science features short publication times after acceptance and colour printing free of charge.
